2023-06-21ARM: dts: Move .dts files to vendor sub-directoriesRob Herring
The arm dts directory has grown to 1559 boards which makes it a bit unwieldy to maintain and use. Past attempts stalled out due to plans to move .dts files out of the kernel tree. Doing that is no longer planned (any time soon at least), so let's go ahead and group .dts files by vendors. This move aligns arm with arm64 .dts file structure. There's no change to dtbs_install as the flat structure is maintained on install. The naming of vendor directories is roughly in this order of preference: - Matching original and current SoC vendor prefix/name (e.g. ti, qcom) - Current vendor prefix/name if still actively sold (SoCs which have been aquired) (e.g. nxp/imx) - Existing platform name for older platforms not sold/maintained by any company (e.g. gemini, nspire) The whole move was scripted with the exception of MAINTAINERS and a few makefile fixups.

However, these capabilities should be described in the device tree so that we do not have to rely on the alias.

git://git.kernel.org/pub/scm/linux/kernel/git/krzk/linux into arm/dt Samsung pinctrl DTS and driver changes for v5.18 Conversion of Samsung pinctrl bindings to dtschema followed up with alignment of DTS files to the dtschema. The entire work consists of three parts but everything should be merged at once to avoid dtschema check errors: 1. Samsung pinctrl driver change necessary to accept new DTS (driver depends on node names and this has to be adjusted because of dtschema). 2. Conversion to dtschema which brings requirement of different naming of the GPIO nodes. 3. DTS commits depending on driver (1) above, which convert all GPIO pin bank names to new naming, required by dtschema. This also includes few cleanups around DTS which are here to avoid any merge conflicts. The Samsung pinctrl driver changes are backwards compatible. However the DTS changes (renaming nodes) could cause problems in out-of-tree or other project implementations of the driver. * tag 'samsung-dt-pinctrl-5.18' of git://git.kernel.org/pub/scm/linux/kernel/git/krzk/linux: (28 commits) arm64: dts: exynos: use dedicated wake-up pinctrl compatible in ExynosAutov9 ARM: dts: s5pv210: align pinctrl with dtschema ARM: dts: s3c64xx: align pinctrl with dtschema ARM: dts: s3c24xx: align pinctrl with dtschema arm64: dts: exynos: align pinctrl with dtschema in ExynosAutov9 arm64: dts: exynos: align pinctrl with dtschema in Exynos7 arm64: dts: exynos: align pinctrl with dtschema in Exynos5433 ARM: dts: exynos: align pinctrl with dtschema in Exynos542x/5800 ARM: dts: exynos: align pinctrl with dtschema in Exynos5410 ARM: dts: exynos: align pinctrl with dtschema in Exynos5260 ARM: dts: exynos: align pinctrl with dtschema in Exynos5250 ARM: dts: exynos: align pinctrl with dtschema in Exynos4412 ARM: dts: exynos: align pinctrl with dtschema in Exynos4210 ARM: dts: exynos: align pinctrl with dtschema in Exynos3250 ARM: dts: s3c64xx: drop unneeded pinctrl wake-up interrupt mapping ARM: dts: exynos: simplify PMIC DVS pin configuration in Peach Pi ARM: dts: exynos: override pins by label in Peach Pi ARM: dts: exynos: simplify PMIC DVS pin configuration in Peach Pit ARM: dts: exynos: override pins by label in Peach Pit ARM: dts: exynos: simplify PMIC DVS pin configuration in Odroid XU ...

2016-08-24ARM: dts: exynos: Use 'hpd-gpios' instead of 'hpd-gpio'Milo Kim
This patch enables getting a HPD GPIO descriptor quicker. The exynos-hdmi driver uses "hpd" for HDMI hot plug detection. static int hdmi_resources_init(struct hdmi_context *hdata) { ... hdata->hpd_gpio = devm_gpiod_get(dev, "hpd", GPIOD_IN); ... } This calls 'of_find_gpio()' and it generates the GPIO consumer ID by referring GPIO suffix. So 'hpd-gpios' is preferred on getting a GPIO descriptor. However, if the device tree uses 'hpd-gpio', then the exynos-hdmi driver always retries to get a GPIO descriptor because the first GPIO suffix is not 'gpio' but 'gpios'. So you always see the debug message below. of_get_named_gpiod_flags: can't parse 'hpd-gpios' property of node '/soc/hdmi@14530000[0]' Use the preferred property, 'hpd-gpios' instead of 'hpd-gpio'.

git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull ARM SoC device-tree changes from Olof Johansson: "Unlike the board branch, this keeps having large sets of changes for every release, but that's quite expected and is so far working well. Most of this is plumbing for various device bindings and new platforms, but there's also a bit of cleanup and code removal for things that are moved from platform code to DT contents (some OMAP clock code in particular). There's also a pinctrl driver for tegra here (appropriately acked), that's introduced this way to make it more bisectable. I'm happy to say that there were no conflicts at all with this branch this release, which means that changes are flowing through our tree as expected instead of merged through driver maintainers (or at least not done with conflicts). There are several new boards added, and a couple of SoCs. In no particular order: - Rockchip RK3288 SoC support, including DTS for a dev board that they have seeded with some community developers. - Better support for Hardkernel Exynos4-based ODROID boards. - CCF conversions (and dtsi contents) for several Renesas platforms. - Gumstix Pepper (TI AM335x) board support - TI eval board support for AM437x - Allwinner A23 SoC, very similar to existing ones which mostly has resulted in DT changes for support.
